- What is a quantum computer? - New Scientist
In a quantum computer, the basic unit of memory is a quantum bit or qubit Qubits are made using physical systems, such as the spin of an electron or the orientation of a photon
- IBM says it will build a practical quantum supercomputer by 2029
All quantum computers rely on quantum bits, or qubits, but some teams make these building blocks from particles of light, others from extremely cold atoms, and in the case of Starling, IBM will
- Quantum computers are on the edge of revealing new particle physics
Quantum computers are beginning to become powerful tools for studying some of the most fundamental forces in the universe – and some of the trickiest to understand Two experiments have used
- Is Googles new Willow quantum computer really such a big deal?
Researchers at the tech giant were the first in the world to demonstrate this feat, known as quantum supremacy, with the announcement of the Sycamore quantum computing chip in 2019 But since then
- Record-breaking quantum computer has more than 1000 qubits
The world’s first quantum computer to exceed 1000 qubits has more than double that of the previous record holder, IBM’s Osprey machine, which has 433 qubits Though having more qubits doesn
- Multiple nations enact mysterious export controls on quantum computers
Technology Multiple nations enact mysterious export controls on quantum computers Identical wording placing limits on the export of quantum computers has appeared in regulations across the globe
- Best quantum transistor yet could lead to more accurate computers
Microwaves can control a single quantum bit more precisely than ever before, creating a device similar to a quantum transistor – and potentially making quantum computers more reliable
- Qubit breakthrough could make it easier to build quantum computers
A Canadian quantum computing start-up claims its new qubit will enable much smaller and cheaper error-free quantum computers But getting there will be a steep challenge To correct its own errors
